Technical Summary

This document provides a mechanism whereby endpoints can request Instant
Message Disposition Notifications (IMDN), including delivery, processing
and read notifications, for page-mode instant messages. The Common Profile
for Instant Messaging (CPIM) data format specified in RFC 3862 is extended
with new header fields that enable endpoints to request IMDNs. A new
message format is also defined to convey IMDNs. This document also
describes how SIP entities behave using this extension.

Working Group Summary

The SIMPLE WG supports advancement of this specification.

RFC Editor Note

Page 4, Introduction, Last Paragraph
OLD

IMDNs include positive delivery, negative delivery (i.e., a message did
not get delivered successfully), read notifications (i.e., a message was
rendered) as well as processed notifications.  By using CPIM header
fields, the IMDN request and delivery are abstracted outside the transport
protocol allowing interoperability between different IM systems.

NEW
This specification defines three categories of disposition types,
"delivery", "processing", and "read".  Specific disposition types provide
more detailed information.  For example, the "delivery" category includes
"delivered" to indicate successful delivery and "failed" to indicate
failure in delivery.

Page 5, Terminology, second-to-last bullet 
OLD 
Disposition type: the type of IMDN that can be requested.  This
specification defines three, namely "delivery", "processing" and "read"
disposition types.

NEW
This specification defines three categories of disposition types,
"delivery", "processing", and "read".
